Korvat
Korvat is a planet at the edge of Cardassian Union territory. It is a Class N planet rich in minerals including Duranium and Osmium .
The planet's environment although capable of supporting life is inhospitable to most humanoids. As such the Cardassians operated a penal facility there, known as the Korvat Prison.
The Prisoners at the penal facility also double as miners. Several Bajoran prisoners were shipped to Korvat during the Occupation of Bajor.
